Hi and Welcome to CC, lizzy37.

10" round tin, 2" deep requires 6 cups of cake batter.
10" round tin, 3" deep requires 8 cups of cake batter.
In baking, the recipes aren't written for each pan size. It's usually necessary to make as many batches of cake batter as is required to adequately fill the size pans you're using.
